- This plate-holder is adapted to hold two photographic plates. Myinvention, however, may be applied to a plate-holder adapted to hold buta single plate. This plateholder has a frame consisting of two sidepieces, a a 0 arranged opposite to and parallel with each other, and twoend pieces, a a, arranged intermediately of them and at or about rightangles. A diaphragm, a extends across the frame-between the side piecesand the end pieces, so as to divide'the space between the side piecesand end pieces into two adjacent compartments.

At each side of the diaphragm a the side pieces and end pieces of theframe of the plate- 40 holder are provided in their opposite faces withgrooves a. These grooves are adapted to receive shutters b b of ordinaryconstruction. The hand-pieces of the shutters extend beyond the endpiece, a and hence may at 5 all times be grasped by the hand. Thediaphragm a is provided on each side with a spring, a, against which aphotographic plate isintended to bear when inserted in the plateholder.The'springuponwhicheachplate-hold- 5o er will rest serves to force theplate outwardly whenever the plate is free to move in that direction.The opposite faces of the end pieces, a? a, are provided with flanges 12 near their outer sides.

Beneath or behind each of the flanges 1 of 5 the end pieces, a a spring,a is arranged.

As shown,such spring consists of a bow-shapedv strip of metal, and isfastened about midway between the ends, by a screw or nail, to the endpiece, a The end pieces, a a, are closed beneath the flanges 1 2 and atthe rear of the recesses formed thereby. The side pieces, a a have noflanges. \Vhen a photographic plate, or a kit or frame fastened to aphotographic plate, is inserted within one of the compartments of theplate-holder'which I have described, one end will be forced against theends of the spring a of that compartment and forced against theresistance offered by the spring into the space which is beneath orhehind the flange l of the end piece, a belonging to that compartment.When the end has been inserted beneath or behind said flange 1,thelatter will prevent the plate from being forced outwardly by thespring a of the compartment into which the plate or kit has been partlyintroduced. The plate or kit can be moved so far into the recess behindthe said flange 1 that the other'end of the plate or kit may be movedtoward the diaphragm a? far enough to pass the flange 2 of the end piecea*. When it shall have passed the said flange 2 and been relieved fromthe force of the hand, the spring a will move it so that it will extendunder the flange 2. Then the 85 plate or kit will be held at the twoends by the flanges 1 2.

The flange 2 is provided about midway between the side pieces, a a witha notch, a",of suitable size for the insertion of a finger or thumb. Theplate or kit may thus be reached by the finger or thumb while held inplace by the flange 2. If the thumb or finger be inserted and pressedagainst the plate or kit, the latter may be moved farther into the re- 5cess which is beneath or behind the opposite flangel of the end piece, aand thus the end which was previously secured by the flange 2 may bereleased from said flange, whereupon the spring a will throw the plateor kit outr00 wardly into a position which will permit of its beingeasily lifted out from the plateholder.

WVhat I have said applies equally well to each compartment of the plateholder.

I have shown in one of the compartments of the plate-holder aphotographic plate only, and in the other compartment I have shown aphotographic plate arranged in a kit. This kit a consists of a thinframe having corner pieces, a, across its central opening at one side ofthe frame and swinging buttons a fastened to the other side of the frameand adaptedto be swung over a plate placed within the central opening.

It will be seen that the kit is of sufficient thickness only that whenthe plate has been placed Within the central opening and betweenthe-said corner pieces and buttons, the surfaces of the plate will beapproximately flush with the surfaces of the kit upon both sides.

What I claim as my invention,and desire to secure by Letters Patent, is-

1. In a photographic-plate holder, the combination of a frame composedof side and end pieces rigidly secured together, the end pieces beingprovided with flanges adapted to secure a photographic plate, one ofsaid end pieces having a notch in its flange, the other ofsaid endpieces having a spring arranged in a recess beneath or behind theflange, and both said end pieces being closed beneath said flanges andat the rear ofthe recesses formed thereby, substantially as specified.

2. The combination, with a photographicplate holder, of akit consistingofa thinframe having a central opening, corner pieces ex tending acrossthe central opening upon one side of the kit, and buttons at the otherside of the kit adapted to be adjusted over the opening, said kit beingofsuch thickness only that when a photographic plate is arranged in saidopening and between said corner pieces and buttons the surface of theplate will be approximately flush with the surfaces of the kit' uponboth sides, substantially as specified.
